Important information
1. The water production listed in the table is an average value, and the difference between the minimum water production of a single membrane element and the nominal value does not exceed 20% of the nominal value.
2. Wet-type membrane elements have been strictly tested before leaving the factory, and use 1 .0% sodium bisulfite (10% propylene glycol antifreeze in winter) solution for storage treatment, and then vacuum packaging, the outer packaging is Cardboard box. In order to prevent the growth of microorganisms during short-term storage, transportation and system standby, it is recommended to soak the components with a protective solution (prepared with RO produced water) containing 1 .0% sodium bisulfite (food grade).
3. The RO produced water in the first hour of operation should be discharged.
4. It is forbidden to add any chemical agents that have an impact on membrane elements during storage and operation.
